Dial into PBX - Soft modem issues

[SharpAdam]

Greetings -


Background:
I'm able to dial into a PBX with no problems using my desktop PC. I've got an external (real modem) attached to it.

When I'm not at the office I use my laptop to dial into PBXs. I don't carry a real modem with me, so I am stuck with the software modem (conexant).

Configuration:
There is an external modem connected to the PBX and I'm able to connect via my desktop using VT-100, 9600, 8, n, 1. I typically get dialed in, press enter and the prompt appears.

Problem:
When I dial into the PBX using my laptop and procomm, when I press enter, an x shows up on screen. If switch to VT-220 or 320 a O with a / through it shows up.

I've tried entering the following modem commands prior to dialing:
at+ms=v32
at+ms=v22
at+ms=v34
at+ms=v22b
at+ms=v32b

Any thoughts?

that can work and sometimes because of windows trying to control the world.. procomm shows 9.6 but you've auto bauded to ? .. i usually try 8, none and 1 at 9.6 then 12 and then (really) 7 space and none at both speeds.. the symptoms seem to indicate a laptop setting not the switch modem.. working for the telco i have used scores of pc's dialing into 100's of boxes, yours is a common problem.. just tweak the setting after connect

Its certainly a problem with the laptop setting. I just can't seem to find the setting that works. I've looked around to try to find the key setting that will make it happy, but still no luck.

Its funny, I can dial into some switches with no problems using the softmodem, but other switches I just can't connect to.
